We present agreements that world class pairs use in particular bidding sequences. In some situations there is a systemic approach. This book gives you an overview of how to treat most of these situations. This should help you and your partner to agree on a chosen style for contested auctions. Since there are numerous kinds of possible situations, it isn't as easy to categorize bidding treatments as it is in uncontested sequences. Trying to create a complete set of agreements to handle every situation is practically impossible. It is important to build an understanding within the partnership that is harmonious and that makes it possible for both partners to analyze situations and come up with choice of bids that are along the same lines.
